Specification of Letters Patent. Application filed February 21, 1908. Serial No. 417,076.

Patented Jan. '26., 1909.

To all whom it may concern:

Be it known that I, PEMBROKE D. HAR- TON, a citizen of the United States, residing object of my invention is to provide a mathe same; Fig. 3, is a cross-sectional view of chine thatwill satisfactorily perform the coating operation, and then-deliver the cake right side up for conveyance to a suitable packaging point.

My m'v'ention is fully shown in the accompanying drawings, in which:

Figure 1., is a sectional elevation, partly in section and partly broken away, showing a cake coating machine made in accordance with my invention; Fig. 2, is a plan view of the same, taken on the line aa, Fig. 1; Fig. 4, is an enlarged view of a portion of the apparatus; and Fig 5, is a perspective view illustrating a detail of, my invention.

In a former application for patent for a machine for accomplishing this work, filed July 9, 1907, Serial No. 382,825, I have shown a belt arranged to receive a coating of icing, upon which cakes are fed, and by means suitably disposed, such cakes are pressed into and pick up a certain portion of the icing, and then are delivered by the belt to a suitable conveyer whereby they are carried to a packaging point.

In the structure forming the subject of my present invention, l'provide a roll for coatmg the cakes, arranged to rotate-in a bath of icing or other coating material and thereby gather a coating of the same for application to crackers or cakes fed thereto; such crackers or cakes in the coated condition passing to suitable means for dislodging them from the means carrying them to the coating roller whereby they may be passed to a suitable conveyer and carried to a packaging point.

In the drawings herewith, 1 represents a frame ca 'ng suitable bearings in which are journa ed various shafts necessary to support chain wheels for driving the various belts necessary to complete the operation of the apparatus. A mam driving shaft 2 being provided from which the other shafts are ven.

The main frame may be of considerable length, and carries an ordinary conveyer belt 3, to which boards 4 are applied, onto which the iced cakes are discharged with the ici face uppermost; such boards being carrie to a suitable packaging point.

Above the main frameis a smaller 'su pl'emental frame 5, which may be integral t erewith, although this point is immaterial, which supplementa frame carries a feeding belt 6 onto which the cakes may be laced from suitable hoppers or laid b hand. passes around-a driving rum 7 at one end, driven in any suitable manner, and around This belt a narrow blade 8 at the opposite end so "as to urge. biade 14 carried by the side bars. From such belt,

the cakes are delivered to a seriesof wires, strings or cords 15'. of-comparatively small size, and set quite close together. These cords pass around a drum 16 at the forward end, which is providedwith a chain wheel 17 driven by a suitable chain 18 from the driving shaft. Disposed within the space formed by the said StIID S or wires, is an icing tank 19, in which a roiler ZO, jou'rnaled in bearings 21 is adapted to move and thereby carry a film of icing, a gage or scraper 22 being employed to regulate as muchas possible the thickness of the icing on the roll. .In order to removethis pan, sup orts 23 are carried by the frame 1, upon which the tray maybe lowered when detached from its normal position, and from such supportsit may be passed through the opening in said frame.

The cakes are fed to the strings or wires 15, and are carried thereby into engagement with the icing roll, and in order to insure their contact therewith so as to pick up the icing on said roll, Iprovide a series of narrow, looselv mounted wheels 25 forming a presser roll which is mounted directly above the icing roll on a shaft 26 somewhat smaller in diameter than the opening 27 in said wheels to receive the same, so that said rolls will have ,m an inclined direction to a series of pulleys 29 carried by an adjustable cross-bar 30, and from thence to an idler pulley 31 back to the i driving ulley.

In or er to insure the feed of the cakes with their iced face over the guides28 I rovide a roller 32 having a series of pins 33 a apted to sweep between said wires or st s and the guides and lift the cakes from the orizontal runs of the wires and turn them onto the inclined runs of thesame; The cakes are carried down on the inclined runs to the point where the wires pass around the pulleys 29, where the; are met by the pins 34 of another roll 35 which lift them from said wires or strings 15 and drop them onto the boards 4 of the conveyer belt 3 with the icing face uppermost. The operation of icing cakes in this manner is carried on continuously, and the feature of my invention is the passage of said cakes over an icing roll and the turning of the same from the carrying wires or strings onto boards whereby they may be conveyed to a packaginglpoint.

order to keep the wires or cords as clean as IHossible so that the cakes will not become f0 when carried by the same, I provide a scraper therefor, consisting of a blade 36 carried by an arm 37 pivotallymounted on the supplemental frame, said arm having a screw 38 whereby the blade may be adjusted with respect to thesaid threads. The pins 33 of the roller 32 are cleaned by pins 39 carried by the arm 37.

To insure a sufficient amount of icing to thoroughly coat the cakes, I provide a supplemental icing plate 40, lyingclose to and I extending beyond the icing roll, which will receive icing from said roll and'fu-rnish addi tional contact for the cakes as they leave the latter.

The icing or coating material within the tank 19 maybe heated if desired, a space 41 at the bottom of the same being in communication by the pipe 42, with a source of hot water or steam.

I claim:

1. The combination, in a cake coating machine, of a conveyer, an icin roll disposed be- .low said conveyer, means or feeding cakes to said conveyer for passage to the icing roll, means for pressing said cakes into the icing, said conveyer having horizontal and inclined portions in its run, and means for lifting said cakes from the horizontal portion of said conveyer and delivering them to the inclined portion of the same.

2. The combination, in a cake coating machine, of a conveyer, an icing roll disposed below said convey er, means for feeding cakes to said conveyer for passage to the icing roll,

said conveyer havin an inclined portion in its run, means for elivering cakes to said inclined portion, and means for removing cakes from said inclined portion and simultaneously turning them to bring the iced face up;

3.
